Check the listing for details. Wolf Tooth Elliptical Direct Mount Chainrings for Shimano Cranks. Condition: New. Listed at 84.95 USD. These chainrings are for Shimano direct mount cranks. The Wolf Tooth chainrings feature our patented Drop-Stop® design for the best wear life, chain retention and mud clearance. Compatibility Shimano XTR M9100, XT M8100, and SLX M7100 series 12 speed cranksets. Our chainring offset matches the offset of Shimano chainrings to replicate the intended chainline for the crankset. Recommendations If you plan to ride in very muddy conditions, we recommend a chainguide or chainkeeper in addition to a clutch-type rear derailleur. Without these precautions, you may experience chaindrops and/or chainsuck.
